【摘要】：雙電源轉(zhuǎn)換開(kāi)關(guān)電器作為消防、地鐵等重要負(fù)荷的末端互投裝置，在工程中得到了廣泛的應(yīng)用，在供電系統(tǒng)中的作用也日趨顯著。近年來(lái)，雙電源轉(zhuǎn)換開(kāi)關(guān)電器行業(yè)在我國(guó)發(fā)展較為迅速。由于雙電源轉(zhuǎn)換開(kāi)關(guān)的技術(shù)水平、可靠性和先進(jìn)性直接影響著使用場(chǎng)所的供電水平，關(guān)系到用電人員的生命安全，所以對(duì)其可靠性和機(jī)械性的要求要高于其他開(kāi)關(guān)設(shè)備。安全可靠性是雙電源轉(zhuǎn)換開(kāi)關(guān)設(shè)計(jì)、制造和選用過(guò)程中最關(guān)鍵的指標(biāo)，而具有大電流承載力的三穩(wěn)態(tài)PC級(jí)雙電源轉(zhuǎn)換開(kāi)關(guān)是未來(lái)發(fā)展的趨勢(shì)。 為了提高現(xiàn)有PC級(jí)雙電源轉(zhuǎn)換開(kāi)關(guān)的操作可靠性，本文對(duì)三穩(wěn)態(tài)的PC級(jí)雙電源轉(zhuǎn)換開(kāi)關(guān)進(jìn)行了結(jié)構(gòu)設(shè)計(jì)，使其能夠更好地克服負(fù)載反力，，從而達(dá)到高效可靠的吸合目的。 根據(jù)所設(shè)計(jì)的目標(biāo)電磁驅(qū)動(dòng)機(jī)構(gòu)的磁場(chǎng)分布特點(diǎn)，分別給出靜態(tài)磁場(chǎng)和瞬態(tài)磁場(chǎng)分析的計(jì)算模型和計(jì)算方程。利用Ansoft有限元分析軟件對(duì)設(shè)計(jì)結(jié)構(gòu)進(jìn)行仿真分析。通過(guò)靜磁場(chǎng)分析得到電磁回路的磁場(chǎng)分布，動(dòng)鐵心在不同位置與磁場(chǎng)力的關(guān)系等，由此通過(guò)對(duì)比、設(shè)計(jì)電磁系統(tǒng)的結(jié)構(gòu)尺寸�；诒倔w結(jié)構(gòu)與外電路、線圈匝數(shù)等參數(shù)設(shè)置，建立了設(shè)計(jì)結(jié)構(gòu)的動(dòng)態(tài)特性仿真模型。根據(jù)不同條件，對(duì)設(shè)計(jì)結(jié)構(gòu)進(jìn)行合閘過(guò)程的仿真分析，得到相應(yīng)的瞬態(tài)特性曲線，并確定三穩(wěn)態(tài)彈簧的反力特性。同時(shí)，對(duì)機(jī)械傳動(dòng)部分進(jìn)行反力歸算，確定電磁鐵合閘時(shí)所受到的機(jī)械反力。通過(guò)特性參數(shù)與設(shè)計(jì)要求進(jìn)行對(duì)比分析，驗(yàn)證設(shè)計(jì)機(jī)構(gòu)的可行性。
[Abstract]:As the terminal switching device of fire fighting, subway and other important load, dual-power switch has been widely used in engineering, and the function in power supply system is becoming more and more obvious. In recent years, the double-power switch electrical industry has developed rapidly in our country. Due to the technical level, reliability and advanced nature of the dual-power switch directly affect the power supply level in the place of use, and related to the safety of the life of the power users, so the reliability and mechanical requirements of the switch are higher than other switchgear. Safety and reliability are the most important indexes in the design, manufacture and selection of dual-power switch, and the three-stable PC switch with high current bearing capacity is the trend in the future. In order to improve the operational reliability of the existing PC double power conversion switch, this paper designs the structure of the three stable PC double power conversion switch, so that it can overcome the load reaction better and achieve the purpose of high efficiency and reliability. According to the magnetic field distribution characteristics of the designed electromagnetic driving mechanism, the calculation models and equations of the static magnetic field and the transient magnetic field analysis are given respectively. Ansoft finite element analysis software is used to simulate and analyze the design structure. Through static magnetic field analysis, the magnetic field distribution of the electromagnetic loop, the relationship between the moving iron core and the magnetic field force in different positions and so on are obtained, and the structural dimensions of the electromagnetic system are designed by comparison. The dynamic characteristic simulation model of the design structure is established based on the parameters such as the structure of the body and the external circuit and the number of turns of the coil. According to different conditions, the simulation analysis of the closing process of the designed structure is carried out, and the corresponding transient characteristic curve is obtained, and the reaction characteristics of the three-stable spring are determined. At the same time, the reaction force of the mechanical transmission part is calculated to determine the mechanical reaction force when the electromagnet is closed. The feasibility of the design mechanism is verified by comparing the characteristic parameters with the design requirements.
